triple disc?
 

Hello,

First a little background. Somewhere around 270,000 I pulled the 47re for a rebuild. Im no trans specialist, but tore down the main case (didn't look at overdrive) and upgraded the 2nd gear band, lever, anchor, servo, accumulator, and installed a transgo shift kit. All the clutches and steels seemed fine.
I also installed a remanned single billet torque converter. I'm not too hard on the truck but somewhere near 300,000 miles one of the cooling lines rusted out and spit fluid everywhere. I didn't notice for a while and it slipped a lot. After fixing and topping off it slipped a lot when it warmed up.
I'm thinking now I need to tear into it again and inspect everything. I don't feel like doing this again, not sure if I'm going to add more horsepower or not in the future, but I'm thinking of upgrading to a triple disc.
Is it ok to get a remanned triple disc or should I get a new one?

Since I'm going triple, I assume I should bite the bullet and get an upgraded flexplate and billet input shaft.

I would go billet input and flex plate for sure, those two are 10-20 years old and gone through who knows what. The converter is up to you, either one will do the job. There are differences internally, but both use the same clutches. Warranty and stall choice/restall is a big factor in the price.
